Jonathan's Antiques purchased an old wooden sled at an auction for $210. Jonathan wants to mark up the sled 60% of the selling price. What would be the selling price of the sled?

well, if the selling price was 210, and that's the 100%, then if he adds 60% to that, the new price will be 160% of 210... well, if 210 is the 100%, what's 160% of that?


\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 210&100\\ x&160 \end{array}\implies \cfrac{210}{x}=\cfrac{100}{160}

solve for "x".
